Chennai metro rail aims to fix seepage issues in phase 1

06 Aug 2021 CW Team

Chennai Metro Rail Limited (CMRL) groundwater has been leaking in the tunnels of the underground range. Therefore, grouting would be done again on the tunnel to reduce the leaking.

After opening the phase-I extension project of the metro rail (within six months), the underground stretch tunnels started witnessing leakages.

The grouting would be done in the underground areas of the Phase-I project as the issue persists there too.

The construction cost of the phase-I project was Rs 3,770 crore for 9 km between Wimco Nagar and Washermenpet. However, the Washermenpet to Tondiarpet stretch's construction is underground, and the remaining is elevated.

According to a few officials, the reason for this problem could be the high water table. Once the grouting is done this issue might not occur.

This issue needs to be fixed as soon as possible as the track circuit gets affected, and then trains have to apply emergency brakes.

They said if the last contractor in the phase-I project had conducted grouting properly, then the issue would not have emerged.

After Delhi and Hyderabad, Chennai Metro is the third-largest metro system in the country. In 2015, the first phase of the project began in the city.
